FAJARDO, J.; CONTRERAS, P.  e  IBANEZ S., M. H.. An eigenvalue analysis of damping in optical thin plasmas. Rev. mex. fis. [online]. 2021, vol.67, n.6, 061502.  Epub 14-Mar-2022. ISSN 0035-001X.  https://doi.org/10.31349/revmexfis.67.061502.

In this work, the behavior of magnetohydrodynamic waves in optically thin plasmas considering dissipative processes, thermal and magnetic diffusion, a given ionization, and the heating and cooling functions are investigated for several particular cases. A numerical eigenvalues analysis of the dimensionless secular equations according to various cases is performed for the entire set of MHD equations.

Palavras-chave : Thin optical plasmas; magnetosonic waves; Alfvèn waves; thermal waves; magnetic diffusion; astrophysical plasmas.
